Uploading User-Defined Functions onto the AMIDAS Website

The AMIDAS website has been established as an online interactive tool for running simulations and analyzing data in direct Dark Matter detection experiments. At the first phase of the website building, only some commonly used WIMP velocity distribution functions and elastic nuclear form factors have been involved in the AMIDAS code. In order to let the options for velocity distribution as well as for nuclear form factors be more flexible, we have extended the AMIDAS code to be able to include user-uploaded files with their own functions. In this article, I describe the preparation of files of user-defined functions onto the AMIDAS website. Some examples will also be given.
